Residual stress redistribution of laser cladded rail
To improve the railway networks, track components with greater durability are essential. To this end, we clad a layer of premium material on railhead to reduce wear and the likelihood of fatigue in an effective manner. The resulting residual stresses generated in both the clad and base metal and change in the microstructure of the substrate can be detrimental to their integrity. We propose to measure their residual stress to validate our finite element model for specimens of high and a low durability.
